Title: Motor for electronic watch and method of producing same
Inventor: URUSU GIJIEERU
IPC: G04C15/00
Filed: 1978-12-05
Abstract: A stepping motor particularly intended for electronic watches comprises two poles connected to a core bearing an elongated coil. The poles are joined at nose portions thereof by interposed elements of a material having a magnetic permeability as close as possible to 1. The one-piece stator may be formed by blanking from a composite band, thus considerably simplifying the problem of positioning the poles of the stator relative to the plate of the watch movement and to the rotor. A method of fabricating the one-piece stators efficiently consists in rolling together two strips of ferromagnetic metal and an interposed fillet of non-magnetic metal, these elements being joined at their edges to form a composite band from which the stators are blanked.

Title: Crank angle position detecting device
Inventor: SHIMIZU HIROKAZU
IPC: F02D45/00
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To improve reliability of a crank angle position detecting device by preventing erroneous detection caused by noise mixing at the time of detecting the reference crank angle position. SOLUTION: This device measures a period of a position signal POS10 outputted by a crank angle sensor, and every time the period is measured, the period ratio between the current value and the previous value is calculated. In the case of the period ratio representing the current value divided by the previous value, if it is at least a first threshold (S/L) larger than 1, the reference crank angle position (tooth chipped portion) is detected, while in the case of the period ratio representing that the period ratio equals to the current value divided by the previous value, if it is not more than a second threshold (S/L-L) smaller than the noise mixing is recognized, thereby forbidding the judgement of the detection of the next reference crank angle position, so as to prevent the erroneous detection.  Furthermore, the second threshold is variably set to be smaller in the unstable state of the engine.

Title: Path transistor logic semiconductor device
Inventor: HASHIMOTO MASAMI
IPC: H03K19/0185
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To attain a stable and high speed circuit operation by adding a 2nd positive level higher than a 1st positive level that is fed to a drain or source electrode to a gate electrode of an Nchannel MOSFET so as to prevent a threshold voltage even in the case of the circuit employing a small number of transistors(TRs). SOLUTION: A reference level 0 is set as a negative level and 1st and 2nd levels E1 , E2 (E1 <E2 ) are set as power supply levels. A level 0 to E1 is fed to terminals 114, 115 acting like source or drain electrodes of a logic MOSFET group 101 and a level 0 to E2 is fed to terminals 110-113 acting like gate electrodes. Even when the level E1 is set to the gate level, in the case that a positive signal is fed to the gate electrode, since the level E2 obtained via a level shift circuit is applied, the level E1 is propagated at a high speed without causing a voltage drop. Moreover, a signal correction circuit 121 ensures the signal level E1 . Furthermore, the signal whose level is 0-E1 is converted into a signal whose level is 0-E2 by a level shift circuit 131 and the converted signal is used for a signal of succeeding circuits.

Abstract: PURPOSE: To determine the shutter speed and aperture value automatically, by constituting the memory means of field light in PLL circuit, and controlling the shutter and iris by the output of PLL circuit.  
     CONSTITUTION: The pulse signal at frequency f i  corresponding to the field light generated from a photoelectric transducer circuit 1 is inputted into PLL circuit 5. In the circuit 5, a voltage control oscillator 10 outputs square wave of frequency f o . When f i =f o , the oscillator 10 outputs a specified frequency. Therefore, when a switch 9 is opened in cooperation with the pressing of the previous stage of the shutter button, a capacitor 29 stores an error DC voltage.
